ELECTRIC-LIGHT FIXTURE;

Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed March 26, 1917. Serial No. 157,329.

To all whom it may concern:

Be it known that I, LINCOLN C. BAIR, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Electric-Light Fixtures, of which the following is a specification.

My invention relates to certain new and useful improvements in lighting fixtures andpertains more particularly to means for suspending the lamps and bowl of an electric light fixture embodying an inverted bowl,

shade, or reflector, in connection with a cen tral support which may be in the form of a chain, spindle, or stem, or a combination of any or all of these.

My device provides means for suspending bowls of different sizes from the same device and also avoids the necessity. of drilling holes in such bowls.

The device embodies a spider which is concealed within the bowl and engages the neck thereof to support the same. The device also embodies nieans for supporting the lamp bulbs in position.

In order that the invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is a central vertical sectional view of the fixture equipped with my iii-- vention.

Fig. 2 is a plan view, partly in section, of the spider and two lamps.

Fig. 3 is a broken detail of a modification.

Referring now in detail to the various parts, A designates an inverted'bowl with an annular contracted neck B, which is engagedby my device.

C designates the suspending means which may be of any'suitable or preferred form.

1 designates the spider constituting the important feature of the invention. Said spider 1 comprises a central member 2, two radial stationary rods 3, and an adjustable rod 4. The stationary rods 3 are, preferably, threaded into the central member 2, while the adjustable rod 4 extends slidably through said member which is provided at one side with a nipple 5, that gives additional supporting surface to the rod .4 and is provided with a set screw 7 for securing rod 4 atany point of its adjustment. The rods 3 and 4 consist, preferably, of heavy wire and the ends of the rods 3 may be cut off if they are too long for the radius of the bowl. The central member 2 is threaded upon the lower end of a tube 9 extending centrally through the lower portion of the suspending means C.

The underside of the central member 2 is internally threaded to receive a screw 10 whereby two lamp brackets 11 are secured to the underside of said member 2, which is hollow as is also the screw 10 for the passage of the electric wires, not shown, which are led down through the 'tube 9, through the central member 2, the screw 10, and into the lamp sockets D.

It will be readily understood from the foregoing that the lamps and the bowl can be readily hung by securing the lamp brackets 11 to the central member 2 with the screw 10 and placing the bowl so that its neck B will rest upon the ends of the stationary rods 3, after which the adjustable rod 4 is moved from the dotted position, Fig. 2, outwardly into engagement with the underside of the neck B. The rod 4 is then secured by the set screw 7, so that it cannot accidentally move inwardly and allow the bowl to fall.

The above is a better and cheaper way than drilling holesin the bowls, which operation often breaks an expensive bowl. However, where the bowl is already drilled as disclosed by the modified form, Fig. 3, the outer ends of the rods are threaded and passed through the drilled holes. Ornamental cap nuts 12 are then screwed upon the threaded ends of the rods, until they bear against the outer surface of the bowl B and prevent it from moving laterally upon the rods.

Reference to Fig. 1, discloses the fact that the spider is concealed within the bowl and as the lamps are arranged below the rods 3 anal 4 there will be no shadows cast by said re s.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In a lighting fixture, a suspension element, a hollow member connected to'said element, a pair of stationary rods threaded at one end into said member, a perforated nipple carried by a side of said member, a rod slidable through the perforation of said nipple and through the member, means to secure the slidable rod to the nipple, a screw threaded into the bottom of said member,

latter against the bottom of said member, said screw being hollow and communlcatlng with the interior of said member to receive the lamp wires and to allow the latter to ex tend through the interior of the member and into and through the suspension element.

2. In a lighting fixture, a suspension element, a hollow member connected to said element, a pair of stationary rods threaded at one end into said member, a perforated nipple carried by a side of said member, a rod slidable through the perforation of said nipple and through the member, means to secure the slidable rod to the nipple, a lamp carrying bracket, and means to secure said bracket to the bottom of the member.

3. In a lighting fixture, a suspension element, a member connected to said element, a pair of rods having their inner ends extending into said member so as to be supported thereby, said member having a perforation extending transversely thereof and completely therethrough, a rod in said perforation so as to be adjustable by sliding same, and means to rigidly secure said slidable rod in adjusted position.-

4. In a lighting fixture, a hollow suspension element, a hollow member connected to the bottom of said element, bowl-carrying rods supported by said member, a lamp carrying bracket, and means for securing said bracket to the bottom part of the member,

said means being formed hollow so as to In testimony whereof I aflix my signature,

in the presence of two witnesses.
